Yes, but this is different:

  int (* foo) [3]

This is a pointer to an array of 3 ints.

And you could pass this to an appropriate function as an argument, to pass the whole array, not just a decayed pointer.

And more generally, I'd group things as unambiguously as possible even in your example:

    int * (foo [3])

to make the intent clearer
